Question 1.
What is gas chromatography primarily used for?
Show hintHide hint
Think about applications in chemistry and environmental testing.
Question 2.
What are the two primary phases in chromatography?
Show hintHide hint
Consider what roles these phases play.
3Question 3.
What does the partition constant (K) indicate?
- It measures compound mass
- It indicates the affinity of a compound for phases
- It indicates temperature effect
Show hintHide hint
Think about how it affects retention time.
4Question 4.
True or False: Higher temperatures lead to lower values of K in gas chromatography.
- True
- False
Show hintHide hint
Remember the relationship between temperature and retention.
Question 5.
Given a mixture of hydrocarbons and alcohols, how would you set up the gas chromatography experiment to separate them effectively?
Show hintHide hint
Think about the interactions of the stationary phase with different functional groups.
Question 6.
Discuss the limitations of using non-selective detectors in complex mixtures. How would you mitigate these issues?
Show hintHide hint
Think about the impact of detector specificity on your results.
